YARN CONTROLLER AND SEPARATR FOR RlNG-SPINNING FRAMES.

SPECIFICATION forming part of Letters Patent No. 745,466, dated December 1, 1903. Application led December 12, 1901. Renewed September 9, 1903. Serial No. 172.529. (No model.)

To @ZZ whom it may concern.-

Beit known that We, JOSEPH E. TICHON and HENRY S. FOSTER, citizens of the United States, residin gat New Bedford, in the county of Bristol and State of Massachusetts, have invented a new and useful Improvement in Yarn Controllers and Separators for Ring- Spinning Frames, of which the following is a specification.

This invention has reference to an improved device to separate the yarn and insure the winding of the yarn on the spindle in doffing the bobbin.

The invention consists in the peculiar and novel construction of the knife-blade and thread-guide and in the combination with the sarne of means for lifting the bobbin off the spindle, as will be more fully set forth hereinafter and more particularly pointed out in the claims.

When the bobbins of a ring-spinning machine have been completed and are removed from the spindles, it is necessary to separate the yarn and also necessary to wind the end of the yarn on the spindle, so that when theV full bobbin is replaced by an empty bobbin the yarn may be at once guided onto and wound on the fresh bobbin. To secure this result, a length of yarn is Wound on the spindle or the bobbin-holder below the bobbin. As the bobbin is lifted ed the spindle the yarn is drawn upward spirally around the spindle and is separated from the yarn on the bobbin. When the empty bobbin is placed on the spindle, the end of the yarn on the spindle is held bythe bobbin7 and when the frame is started the yarn is laid on the bobbin by the reciprocating ring and traveler.

The object of this inventionis to hold the loose end of the yarn on the spindle and separate the same from the yarn on the spindle automatically.

Figure l is a transverse sectional view of part of a ring-spinning frame, showing part of a dofiing device provided with our irnproved yarn holder and separator. Fig. 2 is a front elevation, partly in section, taken on the line X X of Fig. l. Fig. 3 is a top view, partly in section.

VSimilar marks of reference indicate correspending parts in all the gures.

ln the drawings, a indicates the bolsterrail ofa spinning-machine; ci', the spindle, supported on the bolster-rail; b, the ring-rail; b' b', the spinning-rings; h2 b2, the travelers; d3, the sliver delivered to the traveler, and dLAL the yarn end wound on the spindle in dofting. The bobbin c is shown in the drawings lifted from the spindle by the clamp c of the doffing-machine c2, by which the bobbin is lifted o from the spindle. This dofflng-machine may be of any suitable construction. We do not Wish to confine ourselves to any particular construction of this machine, but have illustrated in Fig. 1 a form of dofiing-machine invented by \us.

The yarn-end holder and separator is designed to coperate with some form of doffingmachine. As illustrated in the drawings, the bracket e is secured to the frame of the doffing-machine c2, and on the bracket is supported in sliding bearingsthe shaft e. The frame 'e2 is secured to the end of the shaft e' near the spindles. Aspiral springe3 is placed on the shaft e between the frame e2 and the bracket e, and the collar e4 is adjustably secured to the other end of the shaft to limit the action of the coiled spring. projecting from the frame e2, slides in a bearlng on the bracket e and serves to maintain the vertical position of the frame e2. `f Thel plates e6 e6 of the frame e2 have the faces parallel with the spindles covered with the cushions e' e7, of felt-cloth or other material suitable to hold the yarn ends on the spindles. The separating device is supported on the frame e2 above the spindles. It consists of the knife-blade f, liexibly connected with the frame. In the preferred form the knife-blade is hinged on a support secured to the frame The pin e5,

ward on the spindle, and as soon as the bobbin is lifted above the knife the same resumes the horizontal position and cuts the yarn between the bobbin and the spindle. As the bobbin is lifted the do ding-machine continues its forward movement, so that when the yarn end d4 is separated the cushions hold the yarn on the spindle until the fresh bobbin is placed on the spindle and the yarn end secured.

Having thus described our invention, we claim as new and desire to secure by Letters Patent-- 1. In la yarn controller and separator for ring-spinningmachines,the combination with the spindles, of a yieldingly-supported frame having cushioned surfaces bearing on the spindles and provided with a knife-blade, as described.

2. In a yarn controller and separator, the combination with a cushioned frame bearing on the spindles, of a knife supported on the frame, as described.

3. In a spinning-machine, the combination with the spinning-spindles, of a bobbin doffing-machine, a frame supported on the doing-machine, cushions on the frame bearing on the spindles, and a hinged knife supported on the frame, whereby as a bobbin is lifted off from the spindle the yarn is automatically separated and the end securely held on the spindle, as described.

In testimony whereof We have signed our names to this specification in the presence of two subscribing witnesses.
